There was plenty of water flowing at the Lliw Reservoirs recently and during my walk in the rain I took a number of shots of the fast flowing rivers, trying out different settings and shutter speeds.

I have never been a great fan of slow shutter speeds and the “smooth water” effect it gives with flowing water. However, whilst using a fast shutter speed may show the explosive nature of fast moving water, slower shutter speeds will certainly help to represent the flow.

River Torrents

For the shot above the ISO had to be super high (6400) to allow a shutter speed of 1/1250 at f4.

River Torrents 2

Whereas with this shot the ISO was 100 and shutter speed 1/25 at f4.5.

River Churning

Again, the shot above was taken ISO 6400 with a shutter speed of 1/1250 at f9.

River Churning 2

And this one was taken at ISO 100 and a shutter speed of 1/25 at f7.1

The camera was a Canon 550D and the lens was the Canon EF70 – 300mm IS USM.

And for those who are interested, the changing sounds of the river as the flow varies  alongside the footpath (4:22 mins).
